By definition, everything that is printed out for human consumption is a
message.
Everything that is printed out for consumption by an SQL parser (e.g., in
pg_dump) is encouraged to use SQL quoting rules. But everything that is
intended to be read by humans should use quoting rules that are common in
real-life publishing.
